6.3.2 Analog Input
The analog inputs of ADC3910Dx and ADC3910Sx supports differential and single-ended configuration, with
support for AC coupling and DC coupling. Analog inputs are designed for an input common mode voltage of
1.25V which must be provided externally on each input pin. DC-coupled input signals must have a common
mode voltage that meets the device input common mode voltage range.
The ADC3910Dx and ADC3910Sx has buffered analog inputs which eases design by isolating the input from the
ADC sampling operation.
6.3.2.1 Single Ended Input
The ADC3910Dx and ADC3910Sx can be configured to operate in single ended mode using just the positive
signal input. This operating mode must be enabled via SPI write to register 0x30B. The single ended signal is
connected to the positive input of the ADC and negative input needs to be biased to VCM as shown in Figure
6-3.
